Compare any two graphics cards:
Radeon HD 5830 vs Radeon HD 5850
IntroThe Radeon HD 5830 makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific model. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon HD 5850, which uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular card. It features 1440(288x5) SPUs as well as 72 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe Radeon HD 5850 will be a little bit (more or less 17%) better at texture filtering than the Radeon HD 5830. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5850 is a better choice, and very much so. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
